Journal ArticleDOI
Tapping mode atomic force microscopy in liquids
Paul K. Hansma,Jason Cleveland,Manfred Radmacher,D. A. Walters,P. E. Hillner,Magdalena Bezanilla,Monika Fritz,D. Vie,Helen G. Hansma,Craig Prater,J. Massie,L. Fukunaga,J. Gurley,V. Elings +13 more
TL;DR: Tapping mode atomic force microscopy in liquids gives a substantial improvement in imaging quality and stability over standard contact mode as discussed by the authors, where probe sample separation is modulated as the probe scans over the sample.
Journal ArticleDOI
Short cantilevers for atomic force microscopy
D. A. Walters,Jason Cleveland,Neil H. Thomson,Paul K. Hansma,Mark A. Wendman,G. Gurley,V. Elings +6 more
TL;DR: In this paper, a family of silicon nitride cantilevers ranging in length from 23 to 203 μm were designed and tested, and the frequency spectrum of thermal motion in air and water was measured.
Journal ArticleDOI
Does Abalone Nacre Form by Heteroepitaxial Nucleation or by Growth through Mineral Bridges
Tilman E. Schäffer,Cristian Ionescu-Zanetti,Roger Proksch,Monika Fritz,D. A. Walters,Nils Almqvist,Charlotte M. Zaremba,Angela M. Belcher,Bettye L. Smith,Galen D. Stucky,Daniel E. Morse,Paul K. Hansma +11 more
TL;DR: In this paper, the authors present experimental support for a model of abalone nacre growth that is based on mineral bridges between successive aragonite tablets rather than on heteroepitaxial nucleation.
Journal ArticleDOI
Imaging adhesion forces and elasticity of lysozyme adsorbed on mica with the atomic force microscope
Journal ArticleDOI
Studies of vibrating atomic force microscope cantilevers in liquid
TL;DR: In this article, an atomic force microscope (AFM) design providing a focused spot of order 7 μm in diameter was used to analyze the motion of vibrating cantilevers in liquid.
